Hydraulic Aspects in Design and Operation of Axial-flow Pumps

Optimized Charge Pumps for Subthreshold Operation

Over the last decade, the use of Field Programmable Gate Arrays (FPGAs) has grown from the design verification of digital systems to a wide variety of commercial and space applications for which low power consumption and re-programmability are paramount. To address the issue of low power, researchers have reported FPGAs incorporating a variety of design techniques to improve energy efficiency. ...

The control of variable speed pumps in series operation

This paper presents a simulation model for the operation of two series pumps, the second being driven with variable speed. Although this is not usual for this type of configuration that requires generally both pumps working at the same speed, it seems to be preferred in practice. The model was developed so that to be able to quickly check the efficiency variable speed drives based on real value...

a study on the design of bio-ethanol process from date wastes of sistan and baluchistan province

اتانول کاربردهای متنوعی در صنایع لاستیک سازی، رنگسازی، حلالها ومکمل سوخت خودرو دارد. اتانول برخلاف نفت از جمله مواد تجدیدپذیر محسوب می شود که مشکلات زیست محیطی و آلودگی نیز ایجاد نمی کند. استفاده از اتانول به عنوان مکمل سوختخودروها از جمله مهمترین مصارف صنعتی این ماده بشمار می رود. با توجه به این موضوع تحقیق و توسعه در زمینه تولید اتانول با درجه خلوص بالا در سطح جهان، و نه تنها در کشور های پیشر...

Porous glass electroosmotic pumps: design and experiments.

An analytical model for electroosmotic flow rate, total pump current, and thermodynamic efficiency reported in a previous paper has been applied as a design guideline to fabricate porous-structure EO pumps. We have fabricated sintered-glass EO pumps that provide maximum flow rates and pressure capacities of 33 ml/min and 1.3 atm, respectively, at applied potential 100 V. These pumps are designe...
